IMPROVEMENT IN WRENCHES.

Speciiication forming part ot' Letters Patent No. 164,567, dated June22, 1875 application filed January 16, 1875. i

To all whom vit may concern:

Be it known that I, JAMES NORTON, of Middlebury, in the county ot'Addison and State of Vermont, have invented certain new and useful.Improvements in a Combined Wrench and Oiler; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accom- -panying drawings, and to the lettersot reference marked thereon, which form part of this specification.

The nature of my invention consists in` providing a wrench with anoilereservoir in the handle, or forming the handle hollow to constitutean oil-reservoir, which is so constructed that it can be securely closedagainst leakage, yet be easily and quickly opened by the operator. Italso consists in forming a wrench ot' removable pieces, so that thoseparts that are liable to be worn and broken may be easily and quicklyremoved from the handle and stem and replaced by new parts, thus makinga wrench that can be easily and cheaply repaired by the owner.

In the accompanying drawin g, Figure l is a side View, partly insection, ot' a wrench embodying my invention. Fig. 2 is a cross-sec tionthrough the line .r m, Fig. 1.

A represents the handle of my wrench, formed at one end with the stem O.The handie is made hollow, so as to form an interior chamber, B, for thereception of oil. In the other end of the handle is inserted a screw, J,which is formed at its inner end with a valve, a, to close the entranceb'to the oilchamber. By slightly unscrewing the screw J the oil will owaround the valve a and'out at the side outlet d. E is the stationary jawof thewrench, which is dovetailedl sidewise onto the end of the stem, asshown at h, and is fastened by a screw, D. rlhe stud G, through whichthe adjustingescrew H passes, is in like manner fastened to the stein()by a dovetail,

h1, and secured by a screw, D2. The movable jaw F, operated by the screwH, moves in dovetails h2 in the sides of the stem. By thus att-achin gthe4 parts E F G to the stem by dovetails, they are easily removed incase of breakage or when worn, so as to be replaced by new ones.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. The combination of the wrench-handle A with interior oil-chamber B,having passage b, the screw J, with valve a, and the outlet d, allsubstantially as and for the purposes herein set forth.

2. The stationary head E, provided with a T-shaped or dovetailed groove,fitting over the end of the stem, the two parts secured by means of ascrew, I), substantially' as and for the purpose' set forth.

In testimony that I claim the foregoing as my own I aftix'my signaturein presence of two witnesses.

JAMES NORTON.
